In this paper, phase behavior, ionic conductivity, and current-voltage response were evaluated for gels consisting of imogolite nanotubes crosslinked by dicarboxylic acid in ionic liquid to obtain knowledge for designing their physical and electrochemical properties. The phase behavior and ionic conductivity of the gels vary depending on structure of dicarboxylic acid and polarity of solvent. Furthermore, definite current response of the gel was confirmed against voltage application.
